Alumina hollow bricks
Alumina Hollow Bricks Description
Alumina hollow brick is a kind of new high temperature insulating material,it is produced with smelted and blown in electric furnace, the crystal form is a-Al2O3 microcrystal. Take the alumina hollow sphere as the main body, and it can be made into various shapes. The highest use temperature is 1800 degrees, and the product has high mechanical strength. It is several times of the light weight products, and the volume density is only 1/2 of the corundum products.

1. High operating temperature, which can reach above 1750 degree.
2. Optimize the structure and reduce the weight of the furnace body.
Nowadays, high temperature resistant materials are all of heavy bricks. The bulk density is 2.6-3.0g/cm, while the alumina hollow ball insulating refractory brick is only 1.1~1.5g/cm, under the condition of the same cubic meter volume. The alumina hollow ball insulating bricks can reduce the weight of 1.1-1.9 tons.
